At very low temperatures, low mobility samples exhibit a very broad peak as a function of the magnetic field, in contrast to higher mobility samples, where the weak localisation peak is very sharp. We analyze the experimental data in the context of the localisation length, which allows us to extract, both the localisation length and the phase coherence length of the samples, regardless of their mobilities. This analysis is made possible by the observation that the localisation length undergoes a generic weak localisation dependence with striking universal properties.", "revisions": [ { "version": "v1", "updated": "2012-12-21T04:58:29.000Z" } ], "analyses": { "keywords": [ "highly disordered graphene", "localisation length", "generic weak localisation dependence", "field induced weak localisation peak", "magnetic field induced weak localisation" ], "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable" } } }
